invitation wording dilemma

This is the background:

My parents are deceased.
Fi's parents are paying for the reception and we are paying for everything else.
How do I word the invites?
I have a hard time just putting their names on the invites, like Mr and Mrs blah blah blah.
Something about it just sounds wrong to me.
Also, if we don't put their names on the invites, is it improper to put reception hosted by Mr and Mrs FI's parents on the reception card?

FI does not care either way.

What should I do?

How about:

Together with Mr. and Mrs. Blah BLah, You and FH request the honor of your presence at their marriage celebration, etc.

I think that sounds the best.
